The default rekey interval for vSAN data-in-transit encryption on the VxRail Cluster is 6 hours. This interval specifies how frequently the encryption keys are rotated to ensure secure communication within the cluster. Regular rekeying helps maintain data security by reducing the risk of encryption key compromise.

When deploying a VxRail Cluster with an existing customer-supplied vCenter Server, two key considerations are:

Supports Enhanced Link Mode with other VxRail-managed vCenter Servers: This allows the existing vCenter Server to link with other VxRail-managed vCenter Servers, providing a unified management interface across multiple vCenter instances, enabling seamless operations and better scalability.

Uses customer-defined procedures for vCenter LCM (Lifecycle Management): Since the vCenter Server is customer-supplied, the procedures for upgrading and maintaining it are defined and managed by the customer, rather than being automatically handled by VxRail's built-in lifecycle management tools.

Using the VxRail plug-in, iDRAC settings can be configured by navigating to "Host > Configure > VxRail > iDRAC Configuration." This path allows administrators to directly manage and configure the Integrated Dell Remote Access Controller (iDRAC) settings for individual hosts within the VxRail environment, providing essential remote management and monitoring capabilities.
